Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.9.13
Description
A race condition exists in the Linux kernel, specifically in the net/packet/af packet.c file, which can be exploited by local users through a multithreaded application that makes PACKET FANOUT setsockopt system calls. This can lead to a denial of service (use-after-free) or possibly have other unspecified impacts.
Recommendations
For Linux kernel versions prior to 4.9.13, update to version 4.9.13 or later to resolve the issue. As a temporary workaround, consider restricting the use of the PACKET FANOUT setsockopt system call in multithreaded applications to minimize the risk of exploitation.
